Rheumatoid arthritis （RA） is a common chronic systemic autoimmune disease with synovitis as the main manifestation， which often causes joint swelling and pain or even deformity. It is considered to be an incurable lifelong disease. Although the current Western medicine treatment can alleviate the progression of the disease， it has the clinical limitations of liver injury， cardiovascular complications， and other adverse reactions， along with easy recurrence. Traditional Chinese medicine （TCM） has a long history and has the advantages of individualized treatment and fewer adverse reactions. It can effectively relieve the symptoms of joint swelling and pain in RA patients and slow down the progression of bone destruction， which has attracted wide concern in the medical community. Janus kinase （JAK）/signal transducer and activator of transcription （STAT） signaling pathway is an important intracellular pathway involved in cell proliferation， differentiation， apoptosis， immune regulation， and other biological behaviors， and plays an important role in the pathophysiological process of RA. In recent years， many studies have confirmed that TCM monomers and compounds can inhibit inflammation and angiogenesis by regulating the JAK/STAT signaling pathway， induce apoptosis and inhibit proliferation of fibroblast-like synoviocytes （FLS）， regulate immune response， and thus exert an effect in the treatment of RA. However， there is still a lack of comprehensive and systematic induction and overview. Therefore， by searching the relevant literature in China National Knowledge Infrastructure （CNKI） and PubMed databases from 2009 to 2024， this study described the mechanism of the JAK/STAT signaling pathway in the occurrence and development of RA and summarized the research progress of TCM monomers and compounds in regulating the JAK/STAT signaling pathway in RA intervention. The study aims to provide new ideas and strategies for the clinical treatment of RA with TCM and the research and development of new drugs.

Dry eye disease(DED)is a common ocular surface disorder worldwide, primarily characterized by a loss of homeostasis of the tear film, and frequently associated with meibomian gland dysfunction(MGD), decreased tear film stability, ocular discomfort, and visual impairment. In recent years, factors such as the widespread use of digital devices,the aging population, and environmental changes have contributed to a significant increase in its global prevalence, making it a major public health concern. Red light therapy(RLT), also known as low-level laser therapy(LLLT)or photobiomodulation(PBM), is a non-invasive treatment that utilizes low-energy red or near-infrared light to irradiate tissues. It exerts photobiomodulatory effects to promote cellular repair and functional recovery. This therapy has demonstrated considerable potential in treating various ocular conditions. Its broader clinical application could improve therapeutic outcomes, alleviate patient discomfort and financial burden, and reduce the consumption of healthcare resources, thereby yielding significant socio-economic benefits. This paper systematically reviews the multifaceted mechanisms and application prospects of RLT in managing DED, including its anti-inflammatory effects, improvement of meibomian gland function, promotion of conjunctival goblet cell repair, and alleviation of visual fatigue, aiming to provide a theoretical foundation and practical reference for its clinical adoption.

ObjectiveTo evaluate the clinical efficacy and safety of acupuncture in treating severe Bell's palsy and to explore its potential mechanism by investigating the effect on serum levels of glial cell line-derived neurotrophic factor （GDNF） and nerve growth factor （NGF）. MethodsA randomized， subject-blinded， sham-acupuncture controlled trial was conducted. A total of 130 patients with severe Bell's palsy were randomly allocated into a treatment group or a control group at a 1∶1 ratio. Both groups received conventional western medicine. In addition， the treatment group received acupuncture， while the control group received sham acupuncture， with each session lasting 30 minutes. The treatment course lasted 8 weeks for both groups， followed by a follow-up assessment at week 12. The primary outcome was the proportion of patients achieving House-Brackmann （H-B） grade Ⅱ or lower at week 8. Secondary outcomes included Sunnybrook facial grading system scores at week 0， 4， 8， and 12， the time to satisfactory recovery（the time required to achieve H-B grade≤Ⅱ）， distribution of H-B grades and facial disability index （FDI） scores including the physical function subscale （FDIP） and social/well-being function subscale （FDIS） scores at week 0， 4， 8， and 12， and serum GDNF and NGF levels at week 0， 4， and 8. Adverse events and participants' self-assessments of treatment efficacy were also recorded. ResultsA total of 122 participants completed the study， including 62 in the treatment group and 60 in the control group. An intention-to-treat （ITT） analysis was performed， and missing data were handled using the last observation carried forward （LOCF） method. The proportion of patients achieving H-B grade ≤grade Ⅱ at week 8 was 78.5% （51/65） in the treatment group， significantly higher than 49.2% （32/65） in the control group （P＜0.05）. The Sunnybrook scores， FDIP and FDIS scores increased， while H-B grades decreased at week 4， 8， and 12 in both groups compared to week 0； moreover， improvements in all outcome measures were significantly greater in the treatment group than in the control group （P＜0.05）. The median time to satisfactory recovery was 6 weeks （95%CI： 5.697-6.303） in the treatment group， significantly shorter than 12 weeks （95%CI： 8.314-15.686） in the control group （P＜0.05）. Serum levels of GDNF and NGF were significantly higher in the treatment group at weeks 4 and 8 （P＜0.05）. No serious acupuncture-related adverse events occurred in either group. Adverse events were reported in 5 patients （7.69%） in the treatment group and 4 patients （6.15%） in the control group， with no statistically significant difference between groups （P＞0.05）. Patients' self-assessment of treatment efficacy after 8 weeks treatment was significantly better in the treatment group （P＜0.05）. ConclusionAcupuncture can effectively improve facial nerve function and shorten recovery time in patients with severe Bell's palsy， with a favorable safety profile. The therapeutic mechanism may be associated with the upregulation of serum GDNF and NGF levels.

Renal fibrosis represents the pivotal pathological process driving the progression of chronic kidney disease (CKD) towards end-stage renal disease. Its core manifestations include chronic inflammation, excessive deposition of extracellular matrix (ECM), and tubulointerstitial injury resulting in functional deterioration. Emerging research on the molecular mechanisms underlying renal fibrosis has established that, beyond the canonical Smad-dependent pathway, transforming growth factor-β1 (TGF-β1) also modulates fibrogenesis through non-canonical signaling pathways, notably the mitogen-activated protein kinase (MAPK) and phosphatidylinositol 3-kinase/protein kinase B (PI3K/Akt) cascades. These non-canonical pathways engage in crosstalk with the canonical Smad pathway, synergistically regulating key processes such as ECM metabolism, inflammatory responses, and epithelial-mesenchymal transition (EMT), thereby collectively orchestrating the initiation and progression of renal fibrosis. Notably, various active components derived from traditional Chinese medicine have demonstrated anti-fibrotic efficacy by modulating these pathways, highlighting their promising multi-target therapeutic potential. This review aims to systematically summarize recent advances in understanding the roles of TGF-β1-mediated MAPK and PI3K/Akt non-canonical signaling pathways in renal fibrosis and to discuss potential therapeutic strategies targeting these pathways.

Objective To investigate the effects and underlying mechanisms of total flavonoids of sarcandra glabra(TFFSG)on bone marrow mesenchymal stem cells(BMSCs)and their derived exosomes in immune thrombo-cytopenia(ITP),with a focus on promoting megakaryocyte differentiation and maturation.Methods BMSCs induced by rabbit anti-rat platelet serum(APS)were divided into five groups:a blank control group,an ITP-BMSCs model group,and three TFFSG intervention groups with low(1.95 μg/mL),medium(3.90 μg/mL),and high doses(7.80 μg/mL).The apoptosis rates and the expression levels of apoptosis-related proteins-B-cell lymphoma 2(Bcl-2),Bcl-2-associated X protein(BAX),and Cysteinyl aspartate-specific proteinase-3(Caspase-3)-were assessed.Exosomes were isolated from the blank control group(NC-BMSCs-Exos),the ITP-BMSCs model group(ITP-BMSCs-Exos),and the medium-dose TFFSG group(TFFSG-BMSCs-Exos).Each group's exosomes(5 μg/mL)were co-cultured with megakaryocytic lineage Dami cells for 96 hours.Flow cytometry was employed to evaluate the expression of megakaryocytic differentiation markers(CD41a,CD42b,CD61)and the proportion of polyploid cells(≥4 N)in each group.Western Blot analysis was conducted to examine the expression of p-MEK1/2,MEK1/2,p-ERK1/2,and ERK1/2 across all groups.Results Compared with the ITP-BMSCs model group,the apoptosis rates in all TFFSG intervention groups were significantly reduced(P<0.01).In the medium-and high-dose TFFSG groups,BAX and Caspase-3 expression levels were markedly downregulated,whereas Bcl-2 expression was upregulated(P<0.05,P<0.01).Compared with the ITP-BMSCs-Exos group,the TFFSG-BMSCs-Exos group demonstrated increased expression of CD41a+,CD42b+,and CD61+,a higher proportion of polyploid cells(≥4 N)(P<0.05),as well as elevated ratios of p-MEK1/2 to MEK1/2 and p-ERK1/2 to ERK1/2(P<0.05).Conclusion TFFSG inhibits apopto-sis of ITP-state BMSCs in vitro and promotes megakaryocyte differentiation and polyploidization maturation through BMSC-derived exosomes by activating the MEK1/2-ERK1/2 signaling pathway.

Objective:To investigate the therapeutic effect of combined extracranial-intracranial revascularization on elderly patients with symptomatic chronic internal carotid artery occlusion, and to evaluate its safety and efficacy in the elderly population.Methods:A retrospective analysis was conducted on 35 elderly patients(aged ≥60 years)who underwent combined extracranial-intracranial revascularization for symptomatic chronic internal carotid artery occlusion in the Department of Neurosurgery, Renmin Hospital of Wuhan University from January 2017 to June 2022.The clinical data during hospitalization, as well as the follow-up data within 2 years after operation, were collected and analyzed.Results:A total of 35 cases of combined extracranial-intracranial revascularization were performed on 35 patients.The age at surgery ranged from 60 to 74 years(mean age 65.5 ± 4.2 years). The incidence of reversible neurological deficits within 2 weeks postoperation was 34.3%, and the incidence of focal cerebral infarction within 30 days postoperation was 5.7%.The patency rate of the bridging vessel was 97.1% at 3 months postoperation., and the incidence of focal cerebral infarction during the follow-up period of 30 days to 2 years postoperation was 2.9%.At 3 months after surgery, computed tomography perfusion imaging showed that regional cerebral blood flow(rCBF), regional cerebral blood volume(rCBV), regional mean transit time(rMTT), and regional time to peak(rTTP)were improved compared with those before surgery.The modified Rankin scale score decreased compared to preoperative values, while the Montreal Cognitive Assessment showed improvement in cognitive function compared to preoperative levels(all P<0.05). From 6 months to 1-year postoperation, cerebral angiography showed that 38.7% of the patients had neovascularization of Matsushima grade A or grade B. No cases of cerebral hemorrhage or death was observed during the treatment and follow-up. Conclusions:Combined extracranial-intracranial revascularization is safe and effective for elderly patients with symptomatic chronic internal carotid artery occlusion, which can improve the patient′s hemodynamic disorders, prevent infarction events, and improve the patients′ neurological function and cognitive ability.

Objective To construct a clinical-radiological nomo-gram model for severe mycoplasma pneumoniae pneumonia coinfec-tion with other pathogens(Co-SMPP)in children.Methods The clinical and radiological data of children with severe mycoplasma pneumoniae pneumonia(SMPP)who underwent nucleic acid testing or bronchoalveolar lavage(BAL)were analyzed retrospectively.The data analysis were performed by using SPSS 27.0 software.The group comparison between simple SMPP and Co-SMPP children was conducted by using t-tests,Mann-Whitney U tests,or chi-square tests.Nomogram analysis was performed by using R software and rms packages.The predictive performance of the model was evaluated by using the receiver operating characteristic(ROC)curve.Results A total of 194 SMPP children were included in the study,including 136 cases(70.1％)with simple SMPP,58 cases(29.9％)with Co-SMPP.The fibrinogen and albumin levels were lower in Co-SMPP children[(3.53±0.85)g/L,41.00(39.03,43.68)g/L]than in simple SMPP children[(3.79±0.80)g/L,42.80(41.00,44.40)g/L],with P values of 0.047 and 0.036,respec-tively.The probability of bronchial stenosis and grid shadow were higher in Co-SMPP children than in simple SMPP children,and there were significant differences between the two groups(P＜0.001,P=0.010).The odds ratio of bronchial stenosis in predicting Co-SMPP children was 14.085.The clinical-radiological nomogram model had an area under the curve(AUC)of 0.840,with sensi-tivity and specificity of 0.756 and 0.848,respectively.Conclusion The nomogram model based on clinical-radiological features can effectively predict Co-SMPP.

Robotic surgery, as an increasingly widespread application in the treatment of gastric and colorectal cancer, still faces obvious discrepancies in recommendations, indications, and evidence strength across existing guidelines. This study systematically analyzed 31 relevant guidelines and consensus statements (retrieved from Chinese and English databases from January 2010 to May 2025) from two dimensions: feasibility (effectiveness, safety, etc.) and training quality control.The results showed that colorectal cancer guidelines had a higher proportion (4 guidelines) of "clear recommendations" for robotic surgery, while gastric cancer guidelines predominantly presented "conditional recommendations" or no recommendations. In the training and quality control dimension, although structured suggestions received positive recommendations, more than half were based on low or very low-quality evidence. Evidence mapping indicated insufficient matching between "case-specific recommendations" and evidence grades in the feasibility dimension, while training processes emphasized the importance of standardized systems and team collaboration.The study highlights the existing heterogeneity in evidence-based guidelines for robotic gastrointestinal surgery, with colorectal cancer demonstrating a more mature evidence base and gastric cancer showing notable evidence gaps. It is recommended that future guideline development should strengthen the consistency between recommendation grades and evidence levels, promote high-quality research in upper gastrointestinal surgery, and improve surgeon training and certification systems to facilitate standardized clinical translation of robotic gastrointestinal surgery.

Objective:To investigate the association between high-risk human papillomavirus (hrHPV) persistent infection and vaginal microecology.Methods:A total of 53 women were enrolled in the gynecological clinic of Beijing Obstetrics and Gynecology Hospital from January 2020 to January 2021, including 7 women without HPV and 46 women with hrHPV infection. Among the hrHPV infected women, 24 woemn who did not use any drugs were classified as the observation group and the other 22 women who were given standardized interferon vaginal administration for 3 months were regarded as the treatment group. Vaginal secretions of all women were taken for Gram-stained microecological test at the time of enrollment and at the 4, 8, and 12 month follow-up. HPV turning negative was taken as the end point of follow-up.Results:(1) Women of hrHPV persistent infection in the observation and treatmnet groups had more times of abortions ( P=0.180). (2) The hrHPV negative conversion rate was 17% (4/24) in the observation group and 36% (8/22) in the treatment group, but the difference was not significant ( P=0.183). The median hrHPV negative conversion time were 11.0 months and 7.5 months in the observation and treatment groups, respectively, and the difference was statistically significant ( P=0.001). (3) Vaginal microecology was generally normal at the time of enrollment and at the end of follow-up in women with HPV natural negative conversion in the observation group. While vaginal microecological disorders were more common in women with hrHPV persistent infection in the observation and treatmnet groups, including high vaginal pH value, poor vaginal cleanliness, poor grade of Lactobacillus and increased vaginal clutter bacteria, and the vaginal microecological situation did not improve after the 12-month follow-up. (4) In the treatment group, women who turned HPV negative within six months all had normal vaginal microecology when enrollment (5/5). While those who turned negative six months later had a higher proportion of vaginal clutter bacteria (2/3), a poor grade of Lactobacillus (2/3) and a higher proportion of vaginal dysbiosis (2/3). Conclusions:(1) Interferon therapy could shorten the negative turning time of hrHPV. (2) Women with normal vaginal microecology have the ability to naturally clear hrHPV. (3) The vaginal microecological Gram-stain test has limited value in predicting hrHPV clearance, perhaps due to its inability to detect Lactobacillus subtypes.
